Common techniques for using the set() function in Python:
1. Create a set from a list:
my_list = [1, 2, 2, 3, 3, 3]
my_set = set(my_list)
2.Add an item to a set:
my_set = {1, 2, 3}
my_set.add(4)
3.Remove an item from a set by its value:
my_set = {1, 2, 3}
my_set.remove(3)
4.Check if an item is in a set:
my_set = {1, 2, 3}
if 3 in my_set:
print("The item is in the set.")
5.Get the length of a set:
my_set = {1, 2, 3}
set_length = len(my_set)
6.Loop through the items in a set:
my_set = {1, 2, 3}
for item in my_set:
print(item)
7.Get the union of two sets:
set1 = {1, 2, 3}
set2 = {3, 4, 5}
union_set = set1.union(set2)
8.Get the intersection of two sets:
set1 = {1, 2, 3}
set2 = {3, 4, 5}
intersection_set = set1.intersection(set2)
